Software Development Projects
An interesting single-player game!
- Assigned tasks and organized discussions among five students as the team leader
- Designed the GUI theme (results of OpenJudge submissions) to attract CS students
- Implemented several stage properties and an anti-addict system
Commerce is always not an easy thing.
- Front end: A simple GUI for customers and vendors implemented by Python
- Back end: Operation in the database using SQL, with multiple characteristics like view, trigger, stored procedure, transaction, etc.
